Ah, Stew Mac. Great products and service. Stew Mac stuff has been my pressies for birthdays and Christmas for a few years now:D
I have both of the items you've listed and both are great. The little fret end dressing file has that safe edge which comes in handy for shaping the sharp edges of a nut as well as fret ends. No-one ever notices that I do the end of the nut during a setup, but I know feels a lot better!
I did a couple of guitar repair courses at the local college, I took along the fretting kit and had everything I needed to do the jobs.
If you're ordering from there, the one thing to have a look at is the [url="http://www.stewmac.com/shop/Tools/Measuring_tools/String_Action_Gauge.html"]string action gauge.[/url] It's one of those tools that you'll wonder how you did without it before.
